DIES FOR INDENTING WIRE.

SPECIFICATION forming part of Letters Patent No. 271,178, dated January 23, 1883.

Application filed May 20, 1882. (No model.)

To all whom it may concern I Be it known that I, MAX WlESER, a citize of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Dies for indenting Wire, of which the following is a specification. r

This invention relates to dies for indenting wire, and especially such intended to be used to form the shackles of lead seals.

It consists in a pair of dies, each having its face provided with two parallel series of teeth which are beveled in opposite directions and intersect each other on their beveled edges, the teeth of one series alternating with those of the other, so that the dies are adapted by their joint action to indent the wire on four sides in one operation. Each of the dies is built of plates forming the teeth, respectively, for the purpose of allowing the renewal of the teeth, with the plates being combined an inclosing frame having setscrews adapted to hold the plates in one direction, and having one of its sides fastened by set-screws for holding the plates in the other direction.

This invention is illustrated in the accompanying drawings, in which Figure l is a perspective view, showing the lower die partly broken away and showing the face portion of the upper die without the frame. Fig. 2 shows oneof the plates composing the teeth detached. Fig. 3 is a cross'section, illustrating the action of the dies. Fig. 4 shows the wire.

Similar letters indicate corresponding parts.

The letters A B designate the two dies; G 1), their teeth; 0 D, the plates composing the teeth; E, the inclosing-frame; E, its setscrews E the loose side of the frame, and E the screws whereby this side is fastened.

The teeth (J D are arranged in parallel rows or series, with the teeth of one series alternating with those of the other, while they are beveled or inclined in opposite directions, and in such a manner that their beveled edges intersect each other, as clearly shown. This arrangement of the teeth leads to the formation in the face of each die of an angular channel flanked by the teeth, and in applying the device to use the wire is laid in such channel of the lower die. The upper die is then forced down upon the lower one, when the teeth of one die enter the spaces between the teeth of the other, while the beveled edges of the teeth of each die are opposed to the corresponding edges of the teeth of the other die, and by the ensuing action of the dies the wire is indented on four sides, as indicated in Fig. 4, the indentations of each two sides being opposite to each other and alternating with those of the other two sides. V

It has been customary heretofore to indent the wire in two operations-namely, first, on two sides and then on the other or remaining two sides by means of rollers-and since by my invention the indentations can be produced in one operation considerable time and labor are thereby saved.

When the wire is to be used in making sealshackles a blank space is left in each of the dies, producing a plain space in the wire where the latter is cut to separate the shackles.

The teeth-plates (3 D are laid side by side in the frame, and are held therein flatwise by the set-screws E and edgewise by the loose side of the frame or its screws. By making the indenting-teeth of the independent plates they can be readily renewed when they become worn or broken, which is a desideratum. It should be remarked that the faces of the dies can be made flat, as in this example, or they can be made round. In other words, the dies can be made in the form of rollers.

- What I claim as new, and desire to secure by Letters Patent, is-- 1. The within-described dies for indenting wire, each having its face provided with two parallel series of teeth, which are beveled in opposite directionsand intersect each other on their beveled edges, the teeth of one series alternating with those of the other, whereby the dies are adapted jointly to indent the wire on four sides in one operation.

2. The within-described dies for indenting wire, each having its face provided with two parallel series of teeth which are beveled in opposite directions and intersect each other on their beveled edges, the teeth of one series alternating with those of the other, and each built up of plates forming the teeth, respectively, to permit the renewal of the teeth.

3. The comhinatiomwith the plates form- In testimony whereof l have hereunto set ing the indenting-teeth,of theinclosing frame my hand and seal in the presence of two subhaving set-screws adapted to hold the plates scribing witnesses.
